Q1
When LEDs are off or blinking
Symptom
All LEDs
do not light.
The LINK LED at the
LAN port does not
turn on.
All LEDs are
lighted
Cause
The PJP-MC24 is not turned on.
The power cord is
not connected.
The main or
line circuit breakers
have been tripped.
There is a power outage.
The outlet is not receiving power.
(when other devices cannot be
used either).
The PC or hub is
turned off.
The PJP-MC24 is not connected
properly.
The cable in use is
not a LAN cable.
The PC LAN (network) card is
not functioning properly, or its
connection mode is not
compatible with the PJP-MC24.
Immediately after the power
has been turned on (normal
operation).
The PJP-MC24 is broken.
Solution
Turn the power switch on.
Make sure that the power cord is secured
firmly in the power socket.
If the breaker is switched off, switch it
•
on.
If the breaker is switched on, switch it
•
off and then back on again.
Wait until power returns.
If other devices are not functioning
•
either, have the outlet or wiring fixed.
If other devices are functioning on the
•
same outlet, have the PJP-MC24 fixed.
Confirm that the PJP-MC24 and the
devices connected to it are on. Even if
a device is connected correctly to the LAN
port, the LAN LED will not light unless the
connected device is turned on.
Remove all cords and then reinsert them,
making sure that they click into place.
Make sure that you are not using an
•
ISDN cable (the connectors look exactly
the same, so it can be hard to tell the
difference).
Try switching to a different LAN cable.
•
If other devices are not functioning
•
either, have the outlet or wiring fixed.
If other devices are functioning on the
•
same outlet, have the PJP-MC24 fixed.
Wait for about three seconds for loading
to finish.
Have the PJP-MC24 repaired.
